Git Question

How do I create a master branch in a bare Git repository?

(All done in poshgit on Windows 8):

git init --bare test-repo.git
cd test-repo.git


(Folder is created with git-ish files and folders inside)

git status


fatal: This operation must be run in a work tree
(Okay, so I can't use git status with a bare repo; makes sense I guess)

git branch


(Nothing, it seems the bare repo doesn't contain any branches. Do I have to add them from a cloned repo?)

cd ..
mkdir test-clone
cd test-clone
git clone ../test-repo.git


(I get a warning about cloning an empty repository)

cd test-repo


(The prompt changes to indicate I am on the master branch)

git branch


(Shows no results - eh?)

git branch master


fatal: Not a valid object name: 'master'

Um. So how do I create the master branch in my bare repo?

Answer

A bare repository is pretty much something you only push to and fetch from. You cannot do much directly "in it": you cannot check stuff out, create references (branches, tags), run git status, etc.

If you want to create a new branch in a bare Git repository, you can push a branch from a clone to your bare repo:

# initialize your bare repo
$ git init --bare test-repo.git

# clone it and cd to the clone's root directory
$ git clone test-repo.git/ test-clone
Cloning into 'test-clone'...
warning: You appear to have cloned an empty repository.
done.
$ cd test-clone

# make an initial commit in the clone
$ touch README.md
$ git add . 
$ git commit -m "add README"
[master (root-commit) 65aab0e] add README
 1 file changed, 0 insertions(+), 0 deletions(-)
 create mode 100644 README.md

# push to origin (i.e. your bare repo)
$ git push origin master
